A properly attached, undam-
aged quick-clamping nut can 
be loosened by hand when 
turning the knurled ring in an-
ticlockwise direction.

Never loosen a tight quick-
clamping nut with pliers. Al-
ways use the two-pin span-
ner.

 Insert the two-pin span-

ner as shown in the 
illustration.

Grinding/Cutting Disc

Pay attention to the dimensions of the grinding tools. The 
mounting hole diameter must fit the mounting flange without 
play. Do not use reducers or adapters.

When using diamond cutting discs, pay attention that the di-
rection-of-rotation arrow on the diamond cutting disc and the 
direction of rotation of the machine (see direction-of-rotation 
arrow on the machine head) agree.

See graphics page for the mounting sequence.

To fasten the grinding/cutting disc, screw on the clamping nut 

7

 and tighten with the two-pin spanner; see Section “Quick-

clamping Nut ”.



After mounting the grinding tool and before switching 
on, check that the grinding tool is correctly mounted 
and that it can turn freely. Make sure that the grinding 
tool does not graze against the protection guard or oth-
er parts.

A plastic part (O-ring) is fitted around 
the centring collar of mounting flange 

5

. 

If the O-ring is missing or damaged,

the mounting flange 

5

 must be replaced 

before resuming operation.

Flap Disc



For operations with the flap disc, always mount the 
hand guard 12.

Rubber Sanding Plate



For operations with the rubber sanding plate 14, 
always mount the hand guard 12.

See graphics page for the mounting sequence.

Before mounting the rubber sanding plate 

14

, attach the 

2 spacer discs 

13

 to the grinder spindle

GWS 22-180 H / GWS 22-230 H/JH / GWS 24-180 H /
GWS 24-230 H /JH / GWS 26-180 H / GWS 26-230 B/H).

Screw on the round nut 

16

 and tighten with the two-pin span-

ner.

Note: 

Expect more force to be required to loosen the round 

nut 

16

 (GWS 24-230 JVX).

Cup Brush/Disc Brush



For operations with the cup brush/wheel brush, always 
mount the hand guard 12.

See graphics page for the mounting sequence.

The cup brush/disc brush must be able to be screwed onto 
the grinder spindle until it rests firmly against the grinder 
spindle flange at the end of the grinder spindle threads. Tight-
en the cup brush/disc brush with an open-end spanner.

Note: 

Expect more force to be required to loosen the grinding 

tool (GWS 24-230 JVX).

GWS 26-180 H / GWS 26-230 B / H)



When working with the grinding cup, mount the special 
protection guard 24.

The grinding cup 

25

 should never project further out of the 

protection guard 

24

 than necessary for the respective grind-

ing application. Adjust the protection guard 

24

 accordingly to 

this dimension.

See graphics page for the mounting sequence.
